To all whom t may concern.'

Be it known that I, FREDERICK Lorman, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Journal-BOX Lubricant Devices, of which the following is a specification.

My invention is primarily an improvement on the journal-box lubricant device of my reissued Letters Patent No, 13,2344, dated December 26, 1911, in which a holder for the lubricant in cake-form is spring-supported in the journal-box below the journal and tends to rise toward the latter, and a perforated plate is interposed between the holder 'and journal to permit the springpressure to squeeze the lubricant through the perforations, about which projections are "provided on the upper surface of the plate to form -lubricant-conining spaces and contact with the journal-Surface to reduce friction to the minimum.

The more important objects of my present improvement, while retaining all the advantages of the said former construction, are to materially augment the holding capacity for lubricant of the confining spaces therefor on the perforated plate, besides inducing more freely the supply thereto of the lubricant from the cake and confining it more effectively in the spaces against dislodgment', and incidentally to protect from Wear the journal-contacting parts of the perforated plate.

In the accompanying drawing, Figure l is a view in longitudinal sectional elevation of a journal-boi; provided with my improvenient, the section being taken on line 1, l11 ig. 2; Fig. 2 is a section on the irregular line 2--2, Fig. l, and Fig. 3 is a plan View of the perforated plate.

The journal-box 4 and journal 5 'therein may be of ordinary or any suitable construction, with seats 6 formed on rthe bottom of the box for t-he lower ends of two spiral springs G, 6, the upper ends of which are confined in seats 6,2 on the bottom of afollower-plate 7, shown of dished shape and provided with depending guide-flanges 7 on its lateral edges, this plate forming the spring-supported holder for the lubricating grease 8. A perforated plate f), which seais j upon the cake 8, is of concavo-convex forni and provided with depending guide-flanges Specification of Letters Patent.

9 to overlap the holder 7, substantially asin the aforesaid patent. In the present case, however, the plate i) is formed with a series or" longitudinal corrugations, of thc preferred V-shape in cross-section illustrated, producing trough-shaped chambers 10 extending parallel with each other throughout the length of thc plate with lines of perforations l0 in their lower apexes and the upper apexes forming the lines of contact with the journal-surface to which the plate conforms. End-walls l1, ll connect the depending ilanges 9' and close the ends of the grease-chambers l() and conform toT the cross-sectional shape of the plate', reaching to the upper apexcs, of the corrugations whereby the journal bears also against them and they prevent the grease-from getting out of the chambers at their ends and being wasted by dropping into the journal-box.

The entire plate t), with its depending side-walls D and end-walls ll, may he cast as a whole of suitable metal, sueltas braSs, or the upper-end or bearing portions of the walls 11 may be formed of Babbitt metal, molded into place. f

As will be seen, the capacity of the chambers 10, by extending lengthwise throughout the plate, is greatly increased, causing 'them to present always an abundant quantity of grease to the journal when suppliedthrough the perioi'ations l0 from the cake 8, into which the bases of the troughs project by penetration under the force of the springpressure against the cake, thereby inducing the-constant filling from the latter of the plate-chambers.

What I claim as new and desire to secure by Letters Patent is:-

l. In combination with a journal, a journal-box, and a lubricant device comprising a. lubricant-holder spring-supported to extend in the box below the journal and tend to rise toward it, and a longitudinally-corrugated plate, forming a series of troughshaped lubricarit-chambers provided with openings in their bases, interposed between said holder and journal to bear at the open bases against the lubricant and contact along their upper edges with the journal.

2. In combination with a journal, a jour-` nal-box and a lubricant-devicecomprising a lubricant-holder spring-supported to extend in the box below the journal and tend to rise toward it, and a longitudinally-corrugated late, orming a` series of troughshaped ubrieant-ehambers provided with rows of perforations in their bases7 interposed between said holder and journal to bear at the perforated basesfagainst the lubricant and Contact along their upper edges with the journal. i j

3. In combination with a journal, a jour nal-box and a lubricant-device comprising a lubricant-holder spring-supported to extend in the box below the j ournaland tend to rise toward it, and a plate formed with a series of longitudinal corrugations of V-shape in cross-section, forming trough-shaped lubricant-chambers having rows of perforations in their bases, interposed between said holder and journal to bear at said bases against the lubricant and Contact along their upper apexes with the journal.

4. In combination with a journal, a journal-box and a lubricant-device comprising a lubricant-holderI spring-supported to extend in the box below the ournal and tend to rise toward it, and al longitudinally-corrugated eoneavo-convex plate, forming a series of trough-shaped lubricant-Chambers having in the box below the journal and tend to rise toward it,- and .a concavo-eonve'x plate formed with a serles of longitudinal corrugations of V-shape 1n .cross-section, forming with rows of periorations in their bases, said plate having depending sidewalls and end-walls closing the ends of said chambers and forming bearings .for said journal.
